Resistance in Series and Parallel Apparatus
Product Code : SCL-EAE-11187
Quick answer: The Resistance in Series and Parallel Apparatus is a ready-wired board for verifying the laws of combination of resistances. Known-value ceramic power resistors sit under a printed schematic with 4 mm binding posts, so students connect them in series or in parallel, measure the equivalent resistance and compare it with theory. Lab Exports manufactures it in Delhi for schools and colleges.
Specifications
| Component | Specification |
|---|---|
| Resistors | Ceramic power resistors of known values |
| Terminals | 4 mm safety socket binding posts, nickel-plated brass |
| Base | Insulated, non-conductive panel with printed circuit schematic and non-slip feet |
| Recommended input | 0 to 12 V DC |
How the series and parallel experiment is done
For resistors in series the same current flows through each and the voltages add, so the equivalent resistance is R = R1 + R2 + R3. In parallel the voltage across each branch is the same and the currents add, giving 1/R = 1/R1 + 1/R2 + 1/R3; the combined resistance is always less than the smallest single resistor.
- Place the board flat on a dry bench and connect a low-voltage variable DC supply, staying within 0 to 12 V.
- Link the resistors in series using the binding posts, with an ammeter in series and a voltmeter across the combination.
- Record the current and voltage and calculate the equivalent resistance as V/I.
- Rewire the resistors in parallel and repeat the measurements.
- Compare each measured value with the value calculated from the series and parallel formulae.
The same board shows voltage division across a series chain and current division between parallel branches, and gives students practice in connecting a digital multimeter correctly as an ammeter and as a voltmeter.
