Question

A series circuit contains a 30 e resistor, a 20 resistor, and

a 10 resistor. The power supply provides 100 V to the
circuit
The current in the 10
resistor, to two significant figures, is ______ A.

Answer 1

1.7A is the answer

Step-by-step explanation:

Answer 2

=1.667 A

Step-by-step explanation:

For resistors connected in series, the same current flows trough all the resistors.

Therefore, V= IR (total)

V is the voltage of the supply, I the current through the circuit and R(total) the total resistance calculated calculated by adding the resistance of all the appliances in the circuit.

R (total) = 30+20+10= 60Ω as the value E can be replaced with Ω

V=IR

I=V/R

=100 V/ 60Ω

=1.667 A
