What else can I help you with?
When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
What is resistance on something that is shorted?
It depends on weather it is in a parallel or series circuit. In parallel the entire circuit it is in parallel with is shorted out. In series the total resistance decreases by the amount of the resistor that shorted out. Resistors usually open or change value with use.
Can inserting a resistor in a circuit have an effect similar to an short circuit?
It creates an extra load to the circuit if placed parallel to other circuits. this load approaches the equivalent of a short circuit as the resistance value placed there reduces.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit. For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
Parallel tuned circuit in resonance frequency?
A parallel resonant circuit has at its heart an inductorand a capacitor. These are the two parallel components. They each react to voltage and current 180 degrees out of phase with each other. When we "hit" this circuit, called a parallel tank circuit, or just a tank, with voltage, one component is "putting energy into the circuit" while the other one is "storing it up" and then the two components switch roles. The result is that the tank will oscillate, and the frequency of oscillation will be determined by the value of the capacitor and the inductor.
In a parallel circuit the smallest resistor is 500 ohms. What is the largest value this parallel circuit can have?
500 ohms.
What happens to current in a parallel circuit?
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
Can electricity flow through a parallel circuit?
'Electricity' is the name given to a branch of science; it is NOT a quantity. So your question should read, 'How does an electric current flow through a parallel circuit?'The answer is that a parallel circuit is made up of two or more individual 'branches'. The sum of the currents flowing through each branch is the value of the current being drawn from the supply by the complete circuit.
Why would a measured value of Zs for a circuit be lower than the calculated value?
A lower measured Zs value could be due to measurement errors, variations in the system such as temperature or aging of components, or presence of parallel paths for current flow that were not accounted for in the calculation. It is important to recheck measurements, verify test conditions, and ensure calculations are accurate to identify the discrepancy.
Why ammeter works as short circuited in circuit?
The ammeter is basically a Galvanometer with a small resistance to parallel with it. As we know that, if we connect two resistances in parallel, then the equivalent resistance is equal to the the value which is less than the value of lowest resistance connected in parallel. suppose if we connect 1 ohm & 0.1 ohm in parallel, then the equivalent of it will be 0.0909 ohm (less than 0.1 ohm). means in parallel circuit the equivalent resistance become smaller. as like this a small parallel resistance across galvanometer decreases the value of the value of resistance of it. since it gets very small value, so it connected in series to measure the value of current in the circuit. due to very low resistance, it drops very low voltage on it ( upto can be negligible) so we assume that it works like a short circuit.
Reduce Q factor in parallel RLC?
In general, the way to reduce effective Q in a parallel RLC circuit is to reduce the value of R.
Choose true or falseIf all the resistors in a parallel sub-circuit have the same value the total current can be found by multiplying the current by the number of resistors?
False. The total current in a parallel sub-circuit where all resistors have the same value cannot be found by multiplying the current by the number of resistors. In a parallel circuit, the total current depends on the individual resistor values and how they affect the overall resistance of the circuit.
When resistors are connected in parallel what are the relationships between the voltage drops across the resistor and currents through the resistors?
A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source.

What is the three laws of parallel circuit?
The potential difference remains the same over the components in parallel and the current splits up proportianally to the components conductances. The components conductances add up to give the combined conductance of the parallel circuit. Conductance is 1 / resistance
