For a series circuit then: E T = E 1 = E 2 + E 3 = . . . E n Example: A series circuit consists of three resistors having values of 20 ohms, 30 ohms, and 50 ohms, respectively. Find the applied voltage if the current through the 30 ohm resistor is 2 amps. (The abbreviation amp is commonly used for ampere.) To solve the problem, a circuit ...

between the calculated limits in step 2. Variable resistor: 1. Identify the end terminals and the wiper terminal for the potentiometer. Number them 1, 2 and 3 with 2 being the wiper. 2. Position the ohmmeter between terminals 1-2, 2-3 and 1-3 and record these measured values in Table 1a-3. 3.
When objects are connected in series, the electric current flows through them against the resistance of the first object, then against the resistance of For example, if a motor with a resistance of 48 ohms is connected to the terminals of a current source by two wires, each with a resistance of 1 ohm, the...
V 1 = R 1 x I V 1 = 470 Ω x 0.0174 A V 1 = 8 V V 2 = R 2 x I V 2 = 220 Ω x 0.0174 A V 2 = 3 V (or V 2 = V – V 1 V = 12 V – 8 V) In practice the minus probe of the voltmeter is connected to ground or common and remains there. Measurement are only made by using the plus probe of the multimeter. We are measuring against ground.
Then proceed to step 4-6. b. For parallel connection: connect the resistors in parallel form as shown in figure 2. Then proceed to step 4-6. c. For series-parallel connection, connect the resistors in series-parallel form as shown in figure 3. Then proceed to step 4-6. 3. Then connect the 12v supply to the circuit. 4.

this we note that the 7.1-Ω and 5.8-Ω resistors are connected in series, and their 12.9-Ω equivalent resistance is connected in parallel with the 3.2-Ω resistor. The combination of those three resistors is connected in series with . r. and the 4.5-Ω and 1.0-Ω resistors. Once the current . I. through the battery is known, it can be used to
1.5 ×10 −6 amps of current through a resistance of 2.3 ×10 6 Ω will produce a voltage “drop” equal to 3.45 volts. Notes: It is important for students to understand that metric prefixes are nothing more than “shorthand” forms of scientific notation , with each prefix corresponding to a specific power-of-ten.
There is no current division occurring in a series circuit. Current flow through the component is the same, given by Ohm’s law as V= IR I= V/R Where, R is the equivalent resistance of resistances 0.2 Ohm, 0.3 Ohm, 0.4Ohm, 0.5 Ohm and 12 Ohm. These are connected in series. Hence, the sum of the resistances will give the value of R.
3 ohm & 6 ohm resistor connected in parallel with with 2 ohm resistor series we can get equivalent6 resistance of 4 ohm.
