The circuit is shown as above.
If ε = 3 volt and each resistor has 2 ohm resistance, then what's the potential difference between point B and point D ?
V = I R
R series = R1 + R2 + ..
1/ R parallel = 1/R1 + 1/R2 + ...
The Attempt at a Solution
The circuit is very weird. I don't even know how to start.
