In double notation you are specifying a specific location for a reference (ie Vab is the voltage at ‘a’ with respect to the voltage at ‘b’ , which in your example is the voltage across R2. Vbc is the voltage across R1, and Vac is the combined voltage across both).
What is VAB VA VB?
The equation for relative velocity is as follows: VAB = VA – VB Where: VAB = is the velocity of body A as observed by body B VA = velocity of body A VB = velocity of body B (alternatively, this can be switched around to find VBA, which is the velocity of body B relative to body A.
How do you calculate VAB?
To find the voltage Vab, you just need to apply KVL for the loop on the left including the voltage source V3, R4 and R5 . 10V-5.456V= 4.544V I assume this is Vab? You have it wrong sign, just apply KVL to the loop I said above and do it carefully you will get the correct result.
What does the double subscript AB mean in the voltage designation VAB?
Terms in this set (19)
If point b of the notation Vab is specified as ground potential (zero volts), then a single-subscript notation can be used that provides the voltage at a point with respect to ground. ... The double-subscript notation Vab specifies point a as the higher potential .
What makes resistors parallel?
Resistors are in parallel if their terminals are connected to the same two nodes . The equivalent overall resistance is smaller than the smallest parallel resistor.
What is VAB voltage?
VAB = 8 – 5 = 3 V . This is also called as the Potential across the resistor. Current flows in an electrical circuit in the form of charge whereas potential doesn’t flow or move. Potential difference is applied between two points. The unit of potential difference between two points is Volt.

What is the potential difference between two points?
Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. **Measured in Volts: **Potential difference (p.d.) is measured in volts (V) and is also called voltage.
How is potential difference calculated?
Multiply the amount of the current by the amount of resistance in the circuit. The result of the multiplication will be the potential difference, measured in volts. This formula is known as Ohm’s Law, V = IR.
What is V AB in physics?
The relative velocity is the velocity that the body A would appear to an observer on the body B and vice versa. Mathematically speaking the relative velocity is the vector difference between the velocities of two bodies. Relative velocity = velocity of the body A – velocity of the body B. The equation is: v AB = v A – v B .
What determines total power in a series circuit?
The total power in a series circuit is equal to the SUM of the power dissipated by the individual resistors . ... A parallel circuit has the same voltage across each branch that is equal to the source voltage. The current flowing through a parallel branch is proportional to the resistance of the branch.
What law does v IR represent?
Alternate statements of Ohm’s law are that the current I in a conductor equals the potential difference V across the conductor divided by the resistance of the conductor, or simply I = V/R, and that the potential difference across a conductor equals the product of the current in the conductor and its resistance, V = IR ...
What is voltage divider rule formula?
V (t) (R1/R1+R2) V2 (t) = R2 (v (t) /R1+R2) V (t) (R2/R1+R2) The above circuit shows the voltage divider between the two resistors which is directly proportional to their resistance. This voltage divider rule can be extended to circuits that are designed with more than two resistors.
How do you know if a resistor is in parallel?
A node is a junction in the circuit. Two resistor are in parallel if the nodes at both ends of the resistors are the same . If only one node is the same, they are in series. So, R1 and R2 are in parallel and R3 is in series with R1||R2.
What happens when resistors are connected in parallel?
When resistors are connected in parallel, more current flows from the source than would flow for any of them individually , so the total resistance is lower.
Why do resistors in parallel have the same voltage?
In parallel circuits, the electric potential difference across each resistor (ΔV) is the same . ... In a parallel circuit, the voltage drops across each of the branches is the same as the voltage gain in the battery. Thus, the voltage drop is the same across each of these resistors.
