the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor will be the same as the power source.
For example with a1 watt LEDconnected directly to this circuit without a resistor would show a voltage equal to forward voltage drop of the LED (3.3V), this is because the LED is sinking almost all the current available from the capacitor. However the voltage across the LED is not dropping...
Find the colour of second band of the resistor. View Solution A current of 2 mA is passed through a colour coded carbon resistor with first, second and third rings of yellow, green and orange colours. What is the voltage drop across the resistor? View Solution A current of 2 mA is ...
Calculate the current through the resistorR3shown in the circuit below. Voltage Divider Rule: The voltage divider rule for series resistors works for any number of resistors as long as the total voltage drop is known and the resistors are all series resistors. For a resistorRnin a ...

Let us consider a circuit featuring a single ideal battery connected across a pure resistor. As the battery is ideal, it has no internal resistance. Under these circumstances, the voltage drop across the resistor is independent of its resistance and is equal to the constant EMF of the b...
What is the power dissipated through a resistor with current I=4 A and voltage drop ΔV=2 V? Step 1: Determine the relevant values from the problem statement to plug into the equation for electrical power. The values we need to use to calculate power are voltage ...
It is critical to determine the optimum value for the current-sense resistor (RSENSE). Larger RSENSEvalues increase the series IR voltage drop and power loss; however, this would also minimize the effect of the offset voltage error, as shown in Table 2. For designs that ma...
