To increase the electric current flowing through a circuit, you can use methods such as increasing the voltage, reducing the resistance in the circuit, or adding more power sources.
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
Increasing heat can increase the resistance of the material through which the current flows, which can reduce the flow of electric current. However, in some cases, heat can also increase the kinetic energy of charge carriers, leading to increased current flow in certain materials like semiconductors.
Ohm's Law: V = IR Solving for current: I = V/R To affect the current, you can either change the voltage (more voltage --> more current), or the resistance (more resistance --> less current).
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.

increasing resistance and keeping current constant
Ohm's law. Current is directly proportional to the applied emf and inversely proportional to the resistance in the circuit.
Resistance is not affected by either voltage or current. It is determined only by the cross-sectional area, length, and resistivity of the material. As resistivity is affected by temperature, resistance is indirectly affected by temperature.In the so-called 'Ohm's Law' equation, resistance is a constant. So, if you increase voltage, the resistance remains constant, and the current would increase in proportional to the voltage.
Increasing resistance decreases current.
