Hope you can understand my handwriting...

Answer 2

Answer:

Ammeter is also known as current reading in circuit

To find the current we need the resistance

We know that resistors are in parallel

Req = 1/R1 + 1/R2

= 1/20 + 1/5

= 4ohm.

By Applying, V = IR

I = V/R

= 10/4

= 2.5Amp.

A. The Ammeter reading of this circuit is 2.5Amp.

B. The total resistance of the circuit when the switch kept on is 4ohm.
