Day 4 Parallel Circuits

Front

What is the total resistance of three 9-ohm resistors connected in parallel?

Back

3 ohms

Front

What is the current passing through a 6Ω resistor if the total voltage is 3V?

Back

0.5A

Front

Define reluctance in the context of electrical circuits.

Back

Reluctance is the measure of opposition to the lines of force through a material.

Front

What is resistance in electrical terms?

Back

Resistance is anything that slows down the flow of electric charges, measured in ohms.

Front

In a parallel circuit, what happens if one of the light bulbs burns out?

Back

The rest can still light up.

Front

How do you calculate total resistance in a parallel circuit?

Back

Use the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is the unit of electrical resistance?

Back

Ohm (Ω)

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

Ohm's Law: V = I * R, where V is voltage, I is current, and R is resistance.

Front

What happens to the total current in a parallel circuit when more branches are added?

Back

The total current increases.

Front

What is the effect of resistance on current flow in a circuit?

Back

Higher resistance results in lower current flow.
