## What will happen to the current if the voltage is decreased?

i. Inew = 6 mA (Current is directly proportional to voltage; a halving of the voltage will halve the current. But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current.

### How is current affected by the voltage of the circuit?

Ohm’s law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Why is current different from voltage?

Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge. Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. Voltage is the cause and current is its effect.

What happens when voltage is too high or too low?

When volatge is very high then the value of a current drops very low because Voltage is inversely propotional to the value of current. Electrical power transmission companies do this because they want to reduce the cost of Transmission lines.

## Why does a transmission line decrease voltage when current is low?

If in transmission line amount of current flow is less then the transmission line will not be heated so that the copper loss will be less and it will reduce the line to line voltage drop. Considering these types of matter in the transmission line, we increase the voltage by decreasing the current.

### How does ohm’s law apply to high voltage?

\\\$\\begingroup\\\$ You’re confusing “high voltage” with “high voltage loss”. Ohm’s Law governs the lossof voltage across a resistance for a given current passing through it. Since the current is low, the voltage lossis correspondingly low.
