Current Electricity and Effects of CurrentOleepari
Electric current, potential difference and electric current. Ohm’s law; Resistance, Resistivity,
Factors on which the resistance of a conductor depends. Series combination of resistors,
parallel combination of resistors and its applications in daily life. Heating effect of electric
current and its applications in daily life. Electric power, Interrelation between P, V, I and R
3. What is an electric current? For current to flow you must have a complete circuit A power source is needed to create a POTENTIAL DIFERENCE When these conditions are met free electrons move about inside the metal.
4. Which way does current flow Current Electrons The unit of current is the Ampere (A) The symbol for current is I
5. The ping pong experiment Draw the diagram of the ping pong experiment in your book Explain how the charge carriers (electrons) flow around the circuit. The unit of charge is the coulomb (C) The coulomb is defined as equal to the charge flow in one second when the current is one Ampere. The symbol of charge is Q ∆ Q = I ∆ t To calculate the change in charge in a circuit you must multiply the current by the change in time
6.
7. Basic Electrical Circuits Calculate the charge of the circuits drawn on the board if they were running for 10 s 10 min ∆ Q = I ∆ t V = IR You should know this formula from earlier work Calculate the resistance of the bulb in the circuits drawn on the board
8. What is the unit of current? What is the symbol of current? What is the unit of charge? What is the symbol of charge? What does delta (∆) mean Write these into sentences in your books e.g the unit of charge is..... Can you remember without looking?
