Ohm's Law

Ohms law
Lab# 18












Abstract
The specific objective of this lab is to fructify was to analyze the relationship between voltage and current in a given ohmic resistance.
Introduction
Current is the flow of an galvanising charge, which is expressed in amperes (amps). Voltage is the electromotive force (potential difference), which is expressed in volts. Resistance is the materials opposition to the flow of electric automobile current which is measured in ohms. Ohms Law is the law that states galvanising current is proportional to voltage and inversely proportional to resistance. The ammeter (measures amperes) is connected in series with in a circuit. The voltmeter (measures volts is connected in parallel within a circuit.

Procedure
1.Do not call on on the spot source. Properly wire the circuit with the great power source the voltmeter and the ammeter. Leave the circuit open for resistors and get teachers cheers before moving on.
2.Draw the circuit with resistors where it was left open.
3. utilize the resistor in circuit 1, connect the wires and adjust the power supply so that the current listed first is read on the ammeter. Read and record data in the table.
4.Using the alike resistor adjust the power supply so that the ammeter records the s current. Record the data.
5.Repeat steps 3 and 4 for the heartsease of the circuits.




6.Apply Ohms Law to the data and calculate resistivity
