An electric bulb is connected to a 220V power supply line, if the bulb draws a current of 0.5A, calculate the power of the bulb.

An electric bulb is connected to a 220V power supply line, if the bulb draws a current of 0.5A, calculate the power of the bulb.

Solutions

Expert Solution

The formula for electric power is given by

P = VI

where,

P is the power

V is the potential difference in the circuit

I is the electric current

 

Given-

V = 220V

I = 0.5A

 

To Find out-

We have to determine the power of the bulb

P =?

 

Solution

P = VI

P= 220 x 0.5 A

P = 110 watt

 

 

The power of the bulb is 110 watt

3)When a power source like a battery is connected to a circuit, an electric field pushes electrons within the conducting wires causing them to flow. The electric field exists due to an uneven build up of charge on the surfaces of the wires (called a surface charge gradient). In this set of problems we will explore a simple model of how this all comes about and emphasize the connection between source charges, electric fields, and voltage differences in the context...
