An electric heater works by passing a current of 112 amps through a coiled metal wire, causing it to become red hot. if the resistance of the wire is 0.95 ohms, what voltage must be applied to it?

Voltage, V = 106.4 volts

Explanation:

It is given that,

Current passing through coiled metal wire of electric heater, I = 112 amps

Resistance of the wire, R= 0.95 ohms

We have to find voltage applied to the electric heater. It can be calculated using Ohm's law. Mathematically, it can be written as :

V = 106.4 volts

Hence, this much amount of voltage must be applied to the electric heater.

When a ray of light is directed into a mirror , REFRACTION takes place . the light either bends towards the normal or it bends away from the normal depending on from which medium the light passes to which medium .
