Answer:

2. high or low

Step-by-step explanation:

A circuit with high-diameter connecting wires at a low temperature will have the least electrical resistance.

According to Ohm's law, the current flowing through a current carrying conductor is directly proportional to the potential difference across its terminal and inversely proportional to resistance at a constant temperature.

Mathematically, V = IR.

Where;

V = Voltage

I = Current

R = Resistance

Some of the factors affecting resistance of a wire are;

- The resistance of a conducting wire is inversely proportional to its cross-sectional area (diameter).

- The resistance of a conducting wire is directly proportional to its temperature.
