Question

An electric iron of resistare 20 takes a carent of 5 a calculate the that developed in 30 sec. ​

Answer 1

Answer:

The amount of heat (H) produced is given by the joule’s law of heating as H= Vlt

Where,

Current, I = 5 A

Time, t = 30 s

Voltage, V = Current x Resistance = 5 x 20 = 100V

H= 100 x 5 x 30 = 1.5 x 104 J.

Therefore, the amount of heat developed in the electric iron is 1.5 x 104 J.

Explanation:

The amount of heat (H) produced is given by the joule’s law of heating as H= Vlt

The amount of heat (H) produced is given by the joule’s law of heating as H= VltWhere,

The amount of heat (H) produced is given by the joule’s law of heating as H= VltWhere,Current, I = 5 A

The amount of heat (H) produced is given by the joule’s law of heating as H= VltWhere,Current, I = 5 ATime, t = 30 s

The amount of heat (H) produced is given by the joule’s law of heating as H= VltWhere,Current, I = 5 ATime, t = 30 sVoltage, V = Current x Resistance = 5 x 20 = 100V

The amount of heat (H) produced is given by the joule’s law of heating as H= VltWhere,Current, I = 5 ATime, t = 30 sVoltage, V = Current x Resistance = 5 x 20 = 100VH= 100 x 5 x 30 = 1.5 x 104 J.

The amount of heat (H) produced is given by the joule’s law of heating as H= VltWhere,Current, I = 5 ATime, t = 30 sVoltage, V = Current x Resistance = 5 x 20 = 100VH= 100 x 5 x 30 = 1.5 x 104 J.Therefore, the amount of heat developed in the electric iron is 1.5 x 104 J
