OX
Resistance in a circuit causes the current to become slower.
petunjuk
Resistance limits the flow of current, effectively reducing the amount of current that can pass through.

masalah 2
OX
A bulb will not light up if the circuit is open.
petunjuk
Explanation: In an open circuit, the current cannot flow, so the bulb won’t light up.
masalah 3
OX
Electric current flows from the negative terminal to the positive terminal in a closed circuit.
petunjuk
Explanation: Conventional current flows from the positive to the negative terminal, even though electrons move in the opposite direction.
masalah 4
OX
Voltage is a measure of the rate of flow of electrons in a circuit.
petunjuk
Explanation: Voltage measures the electrical potential energy per unit charge; the rate of flow of electrons is called current.
masalah 5
OX
In a parallel circuit, the total current from the main supply equals the sum of the currents in each branch.
petunjuk
In parallel circuits, the total current is divided among branches, and their sum equals the total current from the source.
masalah 6
OX
The magnetic force is strongest at the center of a bar magnet.
petunjuk
Explanation: The magnetic force is strongest at the ends (poles) of the magnet.
masalah 7
OX
An electric current flowing through a wire produces a magnetic field.
masalah 8
OX
The direction of a magnetic field around a current-carrying wire can be found using the right-hand grip rule.
masalah 9
OX
Only permanent magnets can produce magnetic fields.
petunjuk
Explanation: Electric currents (like from a battery) can also produce magnetic fields.
masalah 10
OX
Faraday’s Law states that the induced voltage is proportional to the number of coils and the rate of change of magnetic flux.
