Question

Three resistors are connected to a 12-volt battery in parallel. The current flow through each resistor is 4 amperes. What is the value of the resistors?

Answer 1

Answer:

Value of each resistor will be 3 ohm

Explanation:

It is given that three are connected to a 12 volt battery in parallel

As we know that voltage across parallel combination is same

So voltage across each resistor will be same as 12 volt

It s given that current across each resistor is amperes

From coulomb's law we know that voltage across any resistor is equal to

V = I R

So resistance will be equal to $R=\frac{V}{I}=\frac{12}{4}=3ohm$

So value of each resistor will be 3 ohm  

Answer 2

Answer:

3 ohm

Explanation:

Voltage, V = 12 V

Current across each resistor, i = 4 A

Let the value of each resistance is R.

By using Ohm's law

V = i x R

12 = 4 x R

R = 3 ohm

Thus, the value of each resistor is 3 ohm.
