Question

An Engine release 100j heat in each Second
with 4r resistance calculate the electric
Potential (v) developed in the device.​

Answer 1

Given:-

• Heat ,H = 100 J

• Resistance ,R = 4 Ω

To Find:-

• Potential Difference ,V

Solution:-

Using Formula

• H = V²/R

Where,

H is the heat produce

V is the Potential Difference

R is the Resistance

Substitute the value we get

→ 100 = V²/4

→ V² = 100×4

→ V² = 400

→ V =√400

→ V = 20v

Therefore,the potential developed in the device is 20 Volts.

Additional Information !!

Potential Difference: The potential difference between two point in an electric circuit carrying some current as the work done to move a unit charge from one point to the other.

Potential difference = Work done /Charge.

• V = W/Q

here

V is the potential difference

W is the work done

Q is the charge

• SI unit of electric potential energy is volt (V).

• 1 volt : The potential difference between two points in a current carrying conductor when one joule of work is done to move a charge of one coulomb from one point to other.

1 Volt = 1Joule/1Coulomb

Answer 2

Answer:

Given :-

Heat (H) = 100 J

Resistance (R) = 4 R

To Find :-

Potential difference (V)

SoluTion :-

H = V² /R

Here,

H = Heat

V = Potential difference

R = Resistance

✯ 100 = V²/4

✯ V² = 100 × 4

✯ V² = 400

✯ V = √400

✯ V = 20 Volt
