Question

For the circuit shown below, By using two method to find the value of R . if the supply voltage V= 12 V and the current in the circuit is I=1 A. Please answer this question

Answer 1

Answer:

R = 12 ohms

Explanation:

It is given that,

Supply voltage is 12 V

Current in the circuit is 1 A

We need to find the resistance of the circuit. Ohm's law gives the relationship between current, voltage and resistance as follows :

V = IR

$R=\dfrac{V}{I}\\\\R=\dfrac{12}{1}\\\\R=12\ \Omega$

So, the resistance of the circuit R is 12 ohms.
