What is Ohm's Law?
Ohm's Law defines power as P = I * R.
Ohm's Law states that R = V / I.
Ohm's Law is I = V + R.
Ohm's Law is V = I * R.
How do you calculate resistance in a circuit?
R = V - I
R = V + I
R = V / I
R = I / V
What is the formula for power in an electrical circuit?
P = I / V
P = V + I
P = V - I
P = V × I
What happens to the total resistance in a series circuit?
The total resistance is only affected by the voltage in the circuit.
The total resistance decreases as more resistors are added.
The total resistance increases as more resistors are added.
The total resistance remains constant regardless of the number of resistors.
How does current behave in a parallel circuit?
Current only flows through one branch in a parallel circuit.
The total current in a parallel circuit is the sum of the currents through each branch.
The total current is divided equally among all branches.
The total current is the maximum current of any single branch.
What is the unit of electrical power?
Watt
Volt
Ampere
Ohm
Name three common components found in electrical circuits.
Diode
Transistor
Transformer
Resistor, Capacitor, Inductor
What is the difference between voltage and current?
Voltage is the amount of electric charge; current is the potential difference.
Voltage is the potential difference; current is the flow of electric charge.
Voltage and current are the same concept in electricity.
Voltage is the speed of electric charge; current is the resistance.
How do you measure voltage in a circuit?
Use a voltmeter and connect its probes across the points of interest in the circuit.
Connect a battery directly to the circuit points.
Measure voltage by checking the current flow in the circuit.
Use a multimeter set to resistance mode.
What is the role of a resistor in a circuit?
To increase the current flow in a circuit.
The role of a resistor in a circuit is to limit current and control voltage.
To convert electrical energy into heat without any control.
To store electrical energy for later use.
What is the effect of adding more resistors in series?
The total resistance remains the same.
The total resistance decreases.
The total resistance fluctuates based on temperature.
The total resistance increases.
What is the purpose of a capacitor in a circuit?
The purpose of a capacitor in a circuit is to store and release electrical energy.
To provide a direct path for current flow.
To convert AC to DC voltage.
To amplify electrical signals in a circuit.
What is the relationship between voltage, current, and resistance?
Resistance is independent of voltage and current.
Voltage is equal to current multiplied by resistance (V = I * R).
Current is equal to voltage divided by resistance (I = V / R).
Voltage is the same as resistance.
How can you measure current in a circuit?
Measure the resistance of the circuit components.
Count the number of electrons flowing through the circuit.
Use a voltmeter connected in parallel with the circuit.
Use an ammeter connected in series with the circuit.
