Question

The circuit has a 3 volt EMF and two ohm resistors. How much power in watts does this circuit draw? A) 4.5 , B) 24, C) 1.13 D) 2.67 E) 0.375 F) 1.5

Answer 1

P = 4.5 watts

Step-by-step explanation:

Given that,

EMF of the circuit, E = 3 volt

The resistance of the resistors, R = 2 ohms

We need to find the power of this circuit. The relation between power, emf and resistance is given by the formula as follows :

`P=(V^2)/(R)`

Substitute all the values,

`P=(3^2)/(2)\\\\P=4.5\ W`

So, the power of this circuit is equal to 4.5 watts.
