WebThere is a voltage drop across each bulb. The sum of the voltage drops is equal to the voltage of the power source, which in this case is a battery. Because the current is the … WebThe supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series circuit is equal to the supply voltage, …

WebStep 2: Re-draw the circuit, replacing each of those series or parallel resistor combinations identified in step 1 with a single, equivalent-value resistor. If using a table to manage variables, make a new table column for each resistance equivalent. Step 3: Repeat steps 1 and 2 until the entire circuit is reduced to one equivalent resistor.

WebTotal current is determined by the voltage of the power supply and the equivalent resistance of the circuit. IT = VT / RT. IT = 125 V/100 Ω. IT = 1.25 A. Current is constant through resistors in series. IT = I1 = I2 = I3 = 1.25 A. The voltage drops can be found using Ohm's law. V1 = I1R1. WebTo verify that resistances in series do indeed add, let us consider the loss of electrical power, called a voltage drop, in each resistor in Figure 2.According to Ohm’s law, the voltage drop, V, across a resistor when a current flows through it is calculated using the equation V = IR, where I equals the current in amps (A) and R is the resistance in ohms (Ω).
