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
