What is Ohm's Law?
Click to flip
Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, given the conductor's resistance remains constant.

How is Ohm's Law used in determining resistance?
Click to flip
Resistance can be calculated using Ohm's Law by rearranging the formula to R = V/I, where R is resistance, V is voltage, and I is current.
Click to flip
What is the unit of resistance called?
Click to flip
The unit of resistance is the Ohm, symbolized by the Greek letter Omega (Ω).

How does Ohm's Law apply to series circuits?
Click to flip
In series circuits, Ohm’s Law applies by using the total resistance (sum of individual resistances) in the formula V = I * Rtotal.

How is Ohm's Law important in troubleshooting circuits?
Click to flip
Ohm's Law allows technicians to identify faulty components by comparing expected and actual measurements of voltage, current, and resistance.
Click to flip
How can Ohm’s Law be applied to parallel circuits?
Click to flip
In parallel circuits, Ohm's Law applies by calculating voltage (same across all branches) and using individual resistances to determine current per branch with I = V/R.
Click to flip
What factors can affect resistance in a material?
Click to flip
Factors that affect resistance include material type, temperature, cross-sectional area, and length of the conductor.
Click to flip
How does Ohm's Law assert itself in power calculations?
Click to flip
Ohm's Law is vital in power calculations using the formula P = IV, linking power (P) with current (I) and voltage (V).
Click to flip
What is the formula for Ohm’s Law?
Click to flip
The formula for Ohm’s Law is V = IR, where V is voltage, I is current, and R is resistance.
Click to flip
Why is understanding Ohm’s Law important for electricians?
Click to flip
Understanding Ohm’s Law is crucial for electricians to effectively design, troubleshoot, and repair electrical systems safely.
Click to flip
In what situation might Ohm’s Law not apply?
Click to flip
Ohm’s Law does not apply in non-ohmic materials, where resistance does not remain constant with changes in voltage and current.
Click to flip
What is the significance of the proportionality in Ohm's Law?
Click to flip
The proportionality in Ohm's Law signifies that as voltage increases, current increases linearly, given constant resistance.
