Current and voltage grade 8

  1. 1. . Ammeter connected in a circuit Ammeter connected in a circuit with one dry cell Q1. What is the reading on the ammeter?
  2. 2. Ammeter connected in a circuit with two dry cells
  3. 3. Q2. Compare the brightness of the bulb with one dry cell to its brightness when there are two dry cells in the circuit. Q3. What is the ammeter reading this time? Q4. What can be inferred about the current passing through the bulb?
  4. 4. Connect the voltmeter as shown in figure 5. Switch on and record the voltage in Table 1. Once the task is done, turn off the switch. Voltmeter connected in a circuit with one dry cell Q5. What is the voltmeter reading?
  5. 5. Add another dry cell to the circuit. Record the voltmeter reading in Table 1. Observe the brightness of the bulb. Once the task is done, turn off the switch. Voltmeter connected in a circuit with two dry cells Q5. What is the voltmeter reading?
  6. 6. Q6. Describe the brightness of the bulb. Q7. What is the voltmeter reading this time? Q8. What can you inferred about the voltage across the bulb? Q9. Refer to the table 1, how are voltage and current related?
  7. 7. hank ou for ening! Than you fo listenin
