Why household appliances should be connected in parallel with the voltage source:
To increase the resistance of the circuit
To decrease the resistance of the circuit
To provide each appliance the same voltage as the power source
To provide each appliance the same current as the power source
Example of mechanical waves is:
Radio waves
X-rays
Light waves
Sound waves
an ideal voltmeter is that which draws:
small current
no current
high current
none of these
The value or current I passing through a conductor is inversely proportional to:
Temperature
Potential difference
e.m.f.
resistance
NOT gate is also called:
Converter
Inverter
Transmitter
Receiver
