FEEE

Ohm is unit of all of the following except

• Inductive reactance

• Capacitive reactance

• Resistance

• Capacitance

All the rules and laws of D.C. circuit also apply to A.C. circuit containing

• Capacitance only

• Inductance only

• Resistance only

• All above

The voltage of domestic supply is 220 V. This figure represents

• Mean value

• r.m.s. value

• Peak value

• Average value

Ohm's law is applicable to

• Semiconductors

• Vacuum tubes

• Carbon resistors

• None of these

The condition for the validity of Ohm's law is that the

• Temperature should remain constant

• Current should be proportional to voltage

• Resistance must be wire wound type

• All of the above

   

Ohm's law is not applicable to

• Semiconductors

• D.C. circuits

• Small resistors

• High currents

Correct form of ohm's law

• I = VR

• V ∝ I

• V = IR

• Above B and C

SI unit of Resistance is:

• volts

• amps

• ohms

• watt

SI unit of Power is:

• volts

• amps

• ohms

• watts

SI unit of voltage is:

• volts

• amps

• ohms

• watts
