Ohm's Law and Power

Procedure for series curcuit troubleshooting theory

1.) Analyze the curcuit 2.) Check the setup 3.) Calculate and measure values 4.) Check the results

Current

A movement of electrical charges around a closed path or circuit.

Voltage increases...

Current flow increases if resistance stays the same.

Va=I×Rt

Find how much Voltage is taken from the resistor.

Series curcuit

Flows in a single path through all the components in a circuit.

Dissipation

Giving off heat

What happens to current when voltage decreases?

It decreases

Open

Occurs when a component provides no path for current flow.

Ohm's law

States the relationship of voltage, current and resistance

Total Resistance

Total resistance of the circuit equal to the sum of each individual resistor

Ohms law equation

V=IR

Voltage drop formula

V=I×Rt

Va

Voltage Applied

Voltage

What makes current flow in a circuit and that resistant is the opposition to current flow.

Ohm's Law states

current is directly proportional to voltage and inversley proportional to resistance.

Reisitance increases...

if current flow decreases if voltage stays the same.

Components in a series curcuit with a changed ohmic value provide

increase or decrease in circuits.

Changed Value

occurs when a components ohmic value increases or decreases

voltage drop

the amount of voltage loss that occurs through all or part of a circuit due to impedance.

Power

the rate at which work is done or energy is needed/used. P=V×I

Rt

total resistance

Short

when a component provides no resistance to current flow. Acts like a piece of wire
