How many resistors (in parallel) are required to carry in line?
Step 1: Given Data
Current
Voltage
Resistance of each resistor
Let the number of resistors in parallel be .
Step 2: Formula Used
Resistance
For number of resistors of resistance in parallel
Step 3: Calculate Equivalent Resistance
According to Ohm's law,
Resistance
Step 4: Calculate Number of Resistors
We know that resistors of resistance are in parallel to give an equivalent resistance of .
Hence, four equal resistors are connected in parallel to the circuit.
