How much current will an electric geyser draw from a 220 V source, if the resistance of the geyser is 110 ohm?
2 A
Ohm’s Law states that the current, I flowing through a given metallic wire in an electric circuit is directly proportional to the potential difference, V across the ends of it, provided its temperature remains the same.
I=VR
R is a constant for a given material at a given temperature and is called its resistance.
In the question, V=220 V and R=110 Ω
⇒I=22010=2 A.
