Question

These electrical currents result when connected to a 230 volt socket.
Radiant heater: 4.4A
Iron: 0.43A
Hotplate : 6.5A
vacuum cleaner: 2.2A
Calculate the resistances.

Answer 1

Answer:

Accg to the ohm's law:

V = I R

R = V/I

1. R = V/I

= 230/4.4

= 52.2ohm

2. R = V/I

= 230/0.43

=534.8 ohm

3. R = V/I

= 230/6.5

= 35.3 ohm

4. R = V/I

= 230/2.2

= 104.5 ohm
