Question

150 joule of heat is produced each second in a 6 ohm resistance find the potential difference across the resistor

Answer 1

Answer:

H=v2/rH=150j/sR=6ohm150=v2/6v2=150x6v2=900V=30volts

Answer 2

Answer:

30V

Explanation:

Given,

Heat/energy produced=150 joule

time=1 second

resistance=6 ohm

To find-potential difference

Formulas for heat energy

H = (VI)t.(cannot be used to find the potential difference in the following questions since the value of current is not given)

H = (I^2R)t.(cannot be used to find the potential difference in the following questions since the value of current is not given)

H = (V^2 /R)T----can be used to find the potential difference

Substitute the given values

150=(v^2/6)*1

150*6*1=V^2

900=V^2

V=$\sqrt{900}$

Potential difference=30V
