Potential difference, voltage, is a force that will cause electrons (negative charges) to move if they can. Voltage is the motive power behind electron flow, and electron flow is the current. In a battery, we have voltage between (or across) the terminals from chemical energy inside. We don't have to have current flow to have the voltage. Some might think of voltage as "electrical pressure" because it is a force. That isn't a bad way to look at it. If we connect some wires and put a light bulb and a switch in series across the terminals of the battery, we have a circuit. If we close the switch, voltage, which was present all the time, will now cause electrons to flow through the wire and light the bulb. The battery has a positive terminal and a negative terminal. The positive terminal will take in electrons and the negative terminal will send them out. Current flows in only one direction. The potential difference created by the battery has energized the circuit and current flowed from the negative terminal of the battery, out through the circuit, and back to the positive one.

8 If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V the current flowing through the circuit is?
There is a simple equation relating voltage (properly potential difference), current and resistance: V=IR Where V=potential difference, I=current and R=resistance So to answer: I=60/12 I=5
When the potential is high the current passing through a conductor it is also high true or false?
I think you mean when the 'potential difference' is high, is the current also high? The answer is that it depends on the impedance (a.c.) or resistance (d.c.) of the circuit. If this remains constant, then raising the potential difference will cause the current to increase too.
What is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
Why terminal potential difference is decrease when current in the circuit is increased?
The terminal potential difference decreases when the current in the circuit is increased due to the internal resistance of the power source. As the current increases, the voltage drop across the internal resistance also increases, leading to a decrease in the terminal potential difference available to the external circuit. This is described by Ohm's Law, V = E - Ir, where V is the terminal potential difference, E is the electromotive force of the source, I is the current, and r is the internal resistance.
What is the difference between constant current bias and current mirror circuit?
current mirror circuit produce more stability as compared to biased circuit.
