Starter question A current of 0.15A flows around a circuit for 1 minute. How much charge flows past any point in this time? Show all working out

The answer Charge = current x time (C) (A) (s) Charge = 0.15 x 60 Charge = 9C Correct it if it’s wrong

Objectives Explain what is meant by electric current and voltage Correctly set up 2 bulbs in series Correctly set up a voltmeter and ammeter and take measurements

In an electric c____, current is the flow of e_______. The bigger the current, the m___ electrons are flowing around the circuit. The w___ carry the electrons from one terminal around the circuit to the other t______. Current lamps ircuit lectrons ore ires erminal

Measuring current I Set up the circuit shown below…… …and then record the current using an ammeter in the places shown below. What do you notice about the readings?The current is the same for each ammeter. In a series circuit the current is the same wherever you measure it. When measuring current ammeters are always placed in series. A A A

The v_____ is a measure of how big a push the e_______ are given as they leave the cell or b_____. The bigger the voltage, the bigger the p___. The cell, battery or p____ s_____ produces the voltage. Voltage lamps oltage lectrons attery ush ower upply

Measuring voltage I V2V2 V3V3 V1V1 Set up the apparatus as shown…… …then record the voltages at the locations shown.What do you notice about the readings? For a series circuit, the sum of the voltages for each component is equal to the voltage across the cell or battery. V 1 = V 2 + V 3 NB Voltmeters are connected in parallel VoltmeterVoltage (V) V1V1 V2V2 V3V

I hate to be negative! But don’t forget the detention tomorrow
