Aswitch is connected in a series circuit. if the contacts on the switch are opened, the resistance of the circuit (including the switch) will ? .

Resistance become infinite

Explanation:

In series circuit when switch is closed then a current is flow which is equal to , here V is voltage and R is resistance

But when switch is open then no current is flow in the circuit

So , this is possible when resistance become infinite

So when switch is open then resistance of the circuit will become infinite

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

in physics zero. in muscle fatigue could be high
