Question

the potential difference between the two terminals of an electric iron is 220 volt and the current flowing through its element is 5 ampere calculate the resistance and the wattage of the electric iron explain in brief

Answer 1

V=IR
V=220 volts
I=5 amp
R=220/5
=44 ohm

Answer 2

Answer:

The resistance is 44 ohms and wattage is 1100 watts.

Explanation:

The “potential difference” or “voltage” is the difference in the electric potential across two points.

So we are given V= 220V

The current (I)flowing through the element=5 ampere

Resistance is calculated using the formula: (Resistance of an electrical circuit is defined as the ratio of the voltage supplied to the electric current that passes through the circuit).

R=V/I  

=220/5=44 ohms  

The wattage is the power which is calculated using the formula :( Wattage is the amount of “work done or the electricity” that is consumed per unit time by an individual electrical appliance).

P=V×I(Where V is the “voltage” and I is the “current”)  

P=220×5=1100 watts
