Question

a 230v potential os applied across a conductor of resistance 155ohm in 8s find the heat generated​

Answer 1

Answer:

2716.096 joules

Explanation:

Given :

• Potential difference (or) voltage = 230 volts = v

• Time consumption takes for = 8 seconds = t

• Resistance of the resistor = 155 Ohms = r

To find :

• Heat generated in the circuit

Using ohms law :

V=I×R

230=I×155

I=230/155

I=1.48 Amperes

H=I²rt

H=1.48²×155×8

H= 2.1904×155×8

H= 339.512×8

H= 2716.096 joules

The heat produced in the circuit is equal to 2716.096 joules

Answer 2

Given:-

• Potential difference = 230v

• Resistance of conductor = 155 ohm.

• Time = 8 s.

To Find:-

• Heat generated.

Solution :-

By the using this formula

➦ H = V²×t/R

➭ H = 230²× 8/155

➭ H = 52900× 8/155

➭ H = 423200/155

➭ H = 2730.32 Joules.

∴ The heat generated is 2730.32 J.
