Q1:

Resistance is measured in ?

A Volts

B Amps

C Watts

D Ohms

E None of the above

ANS:D - Ohms

The three most basic units in electricity are voltage(V) , current(I) and resistance(r). Voltage is measured in volts, current is measured in amps and resistance is measured in ohms.

Electrical power is measured in watts. In an electrical system power(P) is equal to the voltage multiplied by the current.
