Current will remain same

Whole circuit will not function

No current will flow in that branch

Voltage drop increase in the opened branch

Varistors

Sensistors

Thermistors

Light dependent resistor (LDR)

Voltmeter connection

Lighting circuits in home

Shunt resistor in ammeter

Multiplier resistor of a voltmeter

No effect in opened resistor

Full circuit current will flow in opened resistor

Total supply voltage will appear across the opened resistor

No voltage will appear across the opened resistor
