Given a diagram, identify whether a device is an ammeter or voltmeter, and calculate the total resistance. Tip: Know that ammeters go in series and voltmeters go in parallel. 4. Electricity Safety & Household Circuits

Static electricity is the accumulation of electric charges on the surface of an object, typically at rest. It is generated through friction when two objects come into contact and are separated, causing electrons to transfer from one material to another.

What will happen if this charged plastic rod is brought near a stream of neutral tap water? Explain your answer. Exercise 2: Ohm's Law Calculation

1-F (conventional current flows + to – outside; electrons flow – to +), 2-F (parallel – each gets full voltage), 3-T, 4-T, 5-F (1 mA = 0.001 A) Given a diagram, identify whether a device is

triangle at the top of your test sheet immediately. Cover the variable you need to find to see the correct mathematical operation.

A circuit has three resistors of 1 Ω, 3 Ω, and 5 Ω connected in series to a 9 V battery. (a) What is the effective (total) resistance? (b) What is the current flowing through the circuit? (c) What is the voltage across the 3 Ω resistor? What will happen if this charged plastic rod

State the electrical charge of the following subatomic particles: Electron, Proton, Neutron. Answer: Electron – negative (–1 e); Proton – positive (+1 e); Neutron – neutral (0 e).
