Answer:
=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
