What Happens When You Increase The Voltage In A Circuit

The ratio of the resistance stays constant.

What happens when you increase the voltage in a circuit. Would it increase decrease or stay the same. In a passive circuit the resistance is constant so as the voltage applied increases the current will proportionately increase i v r. If current increases in a conductor there will be increased voltage drop in electrical conductors so there will be less voltage at the load. In order for the current to decrease with increasing voltage the circuit must exhibit negative resistance.

When you add more resistors in parallel what happens to a the current. Scroll down to related links and look at ohm s law. What would happen to the total current if you added another resistor in parallel and kept the power supply at 15 v. If you increase the voltage v also the current i must go up.

That is one reason why we use larger cables for higher current flow to reduce voltage loss in the conduct. R v i. When you lift the voltage v that goes to a circuit also the flowing amperage a will go up and so does the power.
