A circuit with a cell of voltage 6V and two resistors of resistance 6 Ohms each connected in parallel. What is the current through the Cell?

Step 1 - draw the circuit.
Step 2- Finding total resistance of resistors in parallel, 1/Rt = 1/R1 + 1/R2 where Rt is the total resistance of the circuit.
Step 3- Use Ohms laws V=IR and rearrange for I to find total resistance of circuit. Where R in this case is Rt and V is 6V.
