The voltage across the resistor R2 will be,V2=VR2R1+R2=12×106+10=7.5VV2=VR2R1+R2=12×106+10=7.5VSummaryThe following points summarize what we discussed in this article −A parallel circuit acts as a current divider circuit because it divides the total circuit current in its all ...
The chopper (2) has two terminals connected to the resistor (1) and is followed by two voltage amplifiers (3,4), a transformer (5), a phase controlled rectifier (6) and a low-pass filter. The filter is the instrument output, and the chopper (2) and rectifier (6) are simultaneously...
We don’t say “transferred” because, in general, the final state or location of the energy is not important. For example, if the voltage across a resistor is 5 V and the current through the resistor is 0.5 A, the resistor is transferring 2.5 W of power (as heat) to the surroundin...
Note that voltage across a resistor is always in phase with the current through it. In the case of a pure inductor or capacitor there is a 90° (π/2) phase shift between the voltage and the current. In the case of the inductor, the current LAGS the voltage, whereas in the capacitor...
Physically, this is occasionally implemented as a potentiometer, which splits a single physical resistor in two with a physically moveable conductive center contact. But most often, it’s two discrete fixed resistors. When a voltage is applied across the pair, the output voltage is some fraction...
The voltage across any resistor in a series connection of resistors shall be equal to the ratio of the ohmic value of the resistor divided by the equivalent resistance of the circuit. This is called the Voltage division rule. For a better idea, let us consider a circuit with two resistors ...
A series connected circuit is often referred to as a voltage divider circuit. The source voltage equals the total of all voltage drops across the series connected resistors. The voltage dropped across each resistor is proportional to the resistance value of that resistor. Larger resistors experience...
Results show that these students tend to perceive such questions in resistance-current terms, with a primary focus on resistor addition, rather than in voltage terms, with two loads being driven from the same source. Common errors in predicting voltages across parallel branches suggest that few ...
going to have to run through R1. The current and voltage across R1produce power, which is dissipated in the form of heat. If that power exceeds the rating of the resistor (usually between ⅛W and 1W), the heat begins to become a major problem, potentially melting the poor resistor. ...
Like a zener diode, it requires an external resistor and operates in parallel with its load (Figure 2). It can be regarded as a voltage-controlled current source between the OUT and GND terminals. Regulation is achieved by adjusting the current level so that VSUPPLY minus the drop across ...
