PRACTICE SOLUTION GRADED A+

◉ Current characteristics in series and parallel circuits.
Answer: In series circuits, current is the same across all components.
In parallel circuits, current adds up.


◉ Ohmmeter.
Answer: A device used to measure resistance in an electrical circuit.


◉ Resistance characteristics in series and parallel circuits.
Answer: In series circuits, resistance adds up. In parallel circuits, the
total resistance is less than the smallest resistance.


◉ Continuity.
Answer: The uninterrupted flow of current in an electrical circuit.


◉ Metric prefixes used on DMM.
Answer: Mega (M), kilo (K), milli (m), micro (μ).


◉ Digital multimeter (DMM).

, Answer: A device used to measure voltage, current, and resistance in
an electrical circuit.


◉ Basic electrical units of measurement.
Answer: Volt (V), ampere (A), ohm (Ω).


◉ Series and parallel resistance.
Answer: The calculation of total resistance in series and parallel
circuits.


◉ Ohm's Law.
Answer: A mathematical equation relating voltage, current, and
resistance in an electrical circuit.


◉ Kirchhoff's Voltage Law.
Answer: The sum of voltage drops in a series circuit is equal to the
applied voltage.


◉ Series and parallel voltage.
Answer: In a series circuit, the current flows through all the
components in the same path. As a result, the total voltage across
the circuit is equal to the sum of the voltages across each of the
components.
