Question

100J heat is generated in a resistance of 4ohm in 1 second.What is the potential difference of the resistor???​

Answer 1

Answer:

The produced heat is given as,

H=I

2

Rt

100=I

2

×4×1

I=25A

The potential difference is given as,

V=IR

=5×4

=20V

Thus, the potential difference across the resistor is 20V.

Answer 2

Given :-

• Heat generated in a resistance = 100 J
• Time = 1 second
• Resistance across the resistor = 4 ohm

To find :-

• Potential difference across the resistor?

Solution :-

★ We know that ★

• Heating effect of electric current.

★ H = l²Rt

→ l² = H/Rt

→ l² = 100/4 × 1

→ l² = 100/4

→ l² = 25

→ l = 5 Ampere

Now, using Ohm's law,

★ V = IR

→ V = 5 × 4

→ V = 20 V

•°• Potential difference across the resistor is 20 V.

More to know :-

• Ohm's Law : Ohm's law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends.
