How do you find the equivalent resistance of a parallel circuit?

How do you calculate two resistors in parallel? Take their reciprocal values, add the two together and take the reciprocal again. For example, if one resistor is 2 Ω and the other is 4 Ω, then the calculation to find the equivalent resistance is 1 / (1/2 + 1/4) = 1 / (3/4) = 4/3 = 1.33.

What is equivalent resistance of the circuit?

The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.

What is equivalent resistance example?

For example, when two 6-Ω resistors are connected in series, it would be equivalent to having one 12-Ω resistor in the circuit. This is the concept of equivalent resistance in a series circuit.

What is the equivalent resistance of the resistors?

The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances. Figure 6.2. 2 (a) Three resistors connected in series to a voltage source. (b) The original circuit is reduced to an equivalent resistance and a voltage source.

How do you solve equivalent resistance problems?

Find equivalent resistance of the network. Find current in each resistor. Find voltage drops VAB,VBC,VCD. Medium.

How do you calculate resistance in a circuit?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

How do you find the equivalent resistance of a Class 10?

The equivalent resistance of a number of resistors connected in parallel can be computed using the reciprocal of the resistance i.e. \frac{1} {R}. The reciprocal of the equivalent resistance will be equal to the sum of the reciprocals of each resistance. The unit of resistance is the Ohm i.e. \Omega.

What is the equivalent resistance of two resistors in parallel?

Two identical resistors in parallel have an equivalent resistance half the value of either resistor.

What is the equivalent resistance of two resistors in series?

The equivalent resistance of two resistors connected in series is the sum of the individual resistances. Figure 19: Two resistors connected in parallel. The reciprocal of the equivalent resistance of two resistances connected in parallel is the sum of the reciprocals of the individual resistances.

What is equivalent resistance in series and parallel?

The method of calculating the circuits equivalent resistance is the same as that for any individual series or parallel circuit and hopefully we now know that resistors in series carry exactly the same current and that resistors in parallel have exactly the same voltage across them.

How do you find the equivalent resistance of a Class 10?

The equivalent resistance of a number of resistors connected in parallel can be computed using the reciprocal of the resistance i.e. \frac{1} {R}. The reciprocal of the equivalent resistance will be equal to the sum of the reciprocals of each resistance. The unit of resistance is the Ohm i.e. \Omega.

What is equivalent resistance?

What is Meant by the Equivalent Resistance? In Physics, an equivalent Resistance is defined as the sum of the resistance of the resistors connected in a circuit. The resistors can be connected in series or parallel. Assume that R1, R2 and R3 be the three resistors.

What is the equivalent resistance in a series circuit

Series circuit: A series circuit is a circuit where the same current flows through each of its components. (It is different from a parallel circuit where the current is divided between the different components.)
