How do you calculate VAB?

Let the two terminals be A and B. Therefore the voltage at A is VA = 15 V and the voltage at B is VB = 5 V. Then the potential difference between A and B is the voltage across the resistor. VAB = VA – VB = 15 – 5 = 10 V.

What does VAB mean in circuit?

difference in potential energy
The value Vab is equal to the difference in potential energy, per coulomb of charge! * In other words Vab represents the difference in potential energy for each coulomb of charge in Q. * Another way to look at it: Vab is the difference in potential energy if the particle has a charge of 1 Coulomb (i.e., Q =1).

How do you find the potential of a point in a circuit?

The potential difference (which is the same as voltage) is equal to the amount of current multiplied by the resistance. A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.

What is the value of VAB in volts?

I already got Vab = – 4.544V and VR5 = 5.456V. That answer is correct when ab is not shorted.

What is voltage AB?

Voltage Polarity An important aspect of any voltage value is its polarity. Voltage is an energy level difference between two points, and the polarity of the voltage simply indicates which point has the higher energy level. The voltage between these two terminals is denoted as VAB.

What is the current through zener diode?

A Zener diode voltage regulator has load requirement of 16 V and 2 Amp. The diode’s minimum current requirement is 2.5 A.

What is the voltage of electricity?

Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
