What is voltage and current relationship?
The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
What is the difference between power voltage and current?
Voltage, also called electromotive force is simply the energy per unit charge. In other words, voltage is the difference in electric potential between two points. Current is just the rate of flow of electric charge….Related Articles:

How to calculate current and voltage in a circuit?
Closes this module. Let’s learn how to calculate current and voltage across each resistor in a circuit. Created by Mahesh Shenoy. This is the currently selected item. Posted a year ago. Direct link to yashodakasarla9876’s post “Sir, why the current remains same in series connec…”
How are current sources different from voltage sources?
In contrast to voltage sources, current sources don’t go well with open-circuits. If there is an open circuit between the two nodes of a current source, that ideal current source will attempt to “force” a current by increasing its voltage.
What happens when a voltage is connected to a circuit?
When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current. In a single (one loop) circuit, the amount of current at any point is the same as the amount of current at any other point.
How can you track voltage in a circuit?
You can then watch how voltage and current distribution change as different parameters in the circuit are adjusted. In this example, we’ll look at a schematic with multiple components and desired measurement points to see how current and voltage can be tracked throughout a circuit.
