Aseries 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.

=1.667 A

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

iron would move it is magnetic there is a mag field around the current in the wire
