Describe two ways to increase the current in a circuit?

1. Increase the voltage while holding the resistance constant.

and

2. Decreasing the resistance while holding the voltage constant.

For a fixed load, increase the supply voltage. For a fixed supply voltage, increase the load.

So that there is no confusion, 'increasing a load' means reducing the resistance (in the case of a d.c. circuit) or reducing the impedance (in the case of an a.c. circuit).
