EEE :: Current Electricity
- Four wires of same material, the same cross-sectional area and the same length when connected in parallel give a resistance of 0.25 Q. If the same four wires are connected is series the effective resistance will be
- When one leg of parallel circuit is opened out the total current will

- Three 6 ohm resistors are connected to form a triangle. What is the resistance between any two corners?
- Two copper conductors have equal length. The cross-sectional area of one conductor is four times that of the other. If the conductor having smaller cross-sectional area has a resistance of 40 ohms the resistance of other conductor will be
