Measurement and Calculations (Post Test)

OHMMETER SCALE: The needle of the meter points at 10. If the range is set to x1, what would be the final answer?

• 1000 ohm

• 100

• 10 Ω

• Ω

OHMMETER: The needle stops at 20, If the range is set to x100 what would be the answer?

• 2000 Ω

• 20 Ω

• 2100 Ω

• 20K Ω

AC SCALE: the desired range is 10V then it stops at 43 what would be the measurement?

• 86 ACV

• 8.6 DCV

• 8.6 ACV

• 0.86 DC

AC SCALE: the desired range is 250V then it stops at 46 what would be the measurement?

• 220 ACV

• 230 ACV

• 23.4 DC

• 22.3 ACV

DC SCALE: If the pointer stopped at division 25 and the range used is 0.25 so the reading is

• 250 DCV

• 125 DCV

• 125 ACV

• 1.25 DCV

DC SCALE: If the pointer stopped at division 34 and the range used is 10 so the reading is

A certain lamp is lighted in a circuit. Measurement indicate, I = 2 A and V = 250 V. Find the Resistance of the lamp

A 15 Ω loud speaker has an applied current of 2 A. Calculate the power dissipated by the loud speaker.

A 40-v source establishes a current of 0.50 A through the lamp. What is the circuit power?

An 8 Ω loud speaker is producing a power of 32 W. What is the current drain?
