Series And Parallel Circuits Worksheet Grade 8 -

Simple drawing

Reasoning (conceptual)

Predicting effects

Short calculations (basic proportional reasoning)

Q8: Two identical bulbs (same resistance) in series: which has larger total resistance, series or parallel? By what factor?

Q9: If one bulb in two identical-series bulbs has resistance R, find equivalent resistance in terms of R.

Troubleshooting / real-world thinking

Challenge (application)

Note: At grade 8, use whole numbers and simple fractions. Avoid decimal-heavy resistance values.

Given a 9V battery and two 3Ω resistors:

Parallel Calculation:

Students look at 6 circuit diagrams and label them as Series, Parallel, or Combination.

Pro Tip: Tell students to trace the wire with their finger. If they hit a junction where they can turn left or right, it’s parallel. If their finger has no choice but to go through every bulb, it’s series. series and parallel circuits worksheet grade 8

Using symbols (—| |— for battery, —o— for bulb), students draw a parallel circuit with 1 battery and 3 bulbs.

Grading check: Look for three separate loops returning to the battery. Simple drawing
