Calculate the total resistance in a series circuit with three resistors of 2ÎĐ, 4ÎĐ, and 6ÎĐ.
R total â =2ÎĐ+4ÎĐ+6ÎĐ=12ÎĐ. Total resistance in series is the sum of all resistors.

In a circuit with two 1.5V batteries connected in series, what is the total voltage?
3V. In series, battery voltages add up, so two 1.5V batteries give 3V total.
