Two resistors when connected in parallel result in an equivalent resistance of 9 ohms. What is the resistance of each resistor?Resistance:It is the conductor's physical property that restricts the flow of electric current in an electrical circuit. It ...
When resistors R(1) and R(2) are connected in a parallel electric circuit, the total resistance is (1)/((1)/(R(1))+(1)/(R(2))). This fraction is equivalent to
If two resistors of R1 and R2 ohms are connected in parallel in an electric circuit to make an R ohm resistor, the value of R can be found from the equation, 1R=1R1+1R2 If R1 is decreasing at the rate of 1 ohm/sec and R2 i increasing at the rate of 0.5 ohm/sec, at what ...
In an electric circuit, the resistors may be connected in various possible combination. Out of that one of the most simple combination is the series combination. In series combination to find the equivalent resistance of the circuit, we simply add all the res...
This paper reports an investigation of the performance of students at age 15 on written diagnostic questions involving the prediction of voltmeter readings in circuits consisting of two resistors in series. The results show that these students have particular difficulty with qualitative questions. Few ...
Consider an electric circuit with three resistors connected in series. The series circuit formula for total resistance is: Rtotal=R1+R2+R3. In the series circuit rules, it is possible to replace many resistors connected in series by one resistor, R total, that has a resistance value equal to...
For MOSFETs no source resistors are required because MOSFETs are negative coefficient transistors and a thermal runaway situation is not applicable to these devices. However still, to ensure high efficiency from the parallel MOSFETs it is recommended to mount them over an adequately rated heatsink....
More than one electrical resistance can be connected in series, in parallel, or in a combination of both. Here, we will mainly discuss series and parallel connections. Resistances in Series Suppose you have three different types of resistors – R1, R2 an
These models are based on an equivalent electrical circuit consisting of lumped circuit elements (resistors, inductors, capacitors and controlled current or voltage sources). The approach includes relations of current–voltage (I–V) and charge/capacitance–voltage (Q/C-V) for nonlinear lumped ...
The components of an electronic circuit can also be the cause of circuit failures. If one of the circuit components is defective, the entire circuit becomes faulty due to the component failure. This component introduces an error in the circuit’s operation. The development of testing strategies ...
