Today we will be finishing off the Ohm's Law assignment.  Make sure you have included photos of each of the circuits that you made yesterday from the Science folder, as well as writing out the Ohm's Law triangle.You also need to answer the four questions repeated below:

1.If the voltage is 3 volts and the current is 5 amps, what is the resistance?
2.If there are 5 volts travelling through a lamp with a resistance of 1.5 ohms, calculate the current:
3.An ammeter reads .87 in a circuit with a resistance of 8 ohms. What is the voltage in the battery?
4. Define current, voltage and resistance.
Once you're finished, hand it to me so I can mark it! You can then continue to work on your practical experiment write ups.
