Question

find out the equivalent resistance when three resistor of resistance R1 R2 and R3 are connected in parallel​

Answer 1

Answer:

∴ ITOTAL = V/REQ = 24/4.8 = 5A. Consider the following circuit where three resistors R1, R2 and R3 are connected in a parallel combination. In parallel resistive circuits, the voltage across each resistor is same and is equal to the supply voltage. Here the supply voltage is V = 12 V.

Step-by-step explanation:

Let I1, I2 and I3 be the currents flowing through R1, R2 and R3 resistors respectively.

Hence, we can write I = I1 + I2 + I3.

According to the Ohm's law,

(Here Req is the equivalent resistance)

∴ The equivalent resistance of a parallel combination is less than the resistance of each of the resistors.
