If a 10-volt battery is placed across a 20-ohm resistance, the current will be amperes. a-200 b-0.5 c-2

The voltage in a circuit is given by the expression , V = IR , Where I is the current inbthe circuit and R is the resistance of circuit.

In this case I = V/R

In this circuit voltage V = 10 volt

Resistance of the circuit = 20 ohm

So current , I = 10/20 = 0.5 amperes

So if a 10-volt battery is placed across a 20-ohm resistance, the current will be 0.5 amperes
