In electrical and electronic circuits,resistanceorelectrical resistanceis defined as the amount of friction in the flow of electric current (or electric charge) offered by the conductor material. The electric circuit element that is used to introduce the electrical resistance in the circuit is called ...
The resistors of certain resistance value can be connected in series or parallel. The current is same throughout the circuit in series connection. The voltage drop is same across each resistor in parallel connection.Answer and Explanation:
If you triple the voltage in a circuit, what happens to the amount of current? Consider 3 resistors with resistances 0.85 times 10^2 ohm, 2.3 k ohm, and 4.5 k ohm. A) What would be their resistance, Rs, in kilo-ohms, if they were connected in series? B) ...
Because more independent paths for electrons to move through ultimately causes more electrons to flow through the circuit, connecting additional resistors in parallel causes the equivalent resistance of the circuit to decrease. The equation for calculating the equivalent resistance of a set of N ...
There are many ways to measure resistance: ohmmeter, volt-ampere, volt-volt, ampere-ampere, bridge, substitution, comparison, half-deviation and so on. No matter what the method is, the experimental principle is no more than partial circuit Ohm's law and
Figure 5.Add the Thevenin voltage to the equivalent circuit schematic. Step 3: Replace the Power Sources To find the Thevenin series resistance for our equivalent circuit, we now must remove the power sources from our circuit in Figure 3 and replace them with short circuit wires, as illustrated...
crosses a resistor, which impedes current flow. In a series circuit, the current lessens with each resistor it crosses. In a parallel circuit, the resistors are placed in such a way that they are all receiving the same amount of current. Current and resistance can be calculated using Ohm's...

How to measure voltage with a tester - choose the voltage (unit "V") parameter, then insert the test leads (black and red). Connect to a circuit and read the value.
Power in Series and Parallel Circuits Power is a measure of the rate of work. Per the physics law of conservation of energy, the power dissipated in the circuit must equal the total power applied by the source(s). Therefore, an interesting rule for total circuit power versus individual compo...
