HOMEWORK -1-

Circuit with one resistor

Brown, green, red, gold

First digit=1, second digit=5, multiplier 100, tolerance= 5%
15x100=1500 1,5 k ohms
R = V/I 9 V : 6 I = 1,5 kilo ohms
I = V/R 9 V : 1,5 ohms = 6 ampere
V = IxR 6 x 1,5 = 9 V
6 x 1,5 ohms = 9
9 volt battery
* What is the voltage across the resistor

Voltage drop is 0,1,4 V

* What is the current through the resistor

6 amp

* What happens to the current and voltage if you double the resistor value

Current stays the same and voltage doubles

* What happens to the current and voltage if you half the resistor value

Current stays the same and voltage is split in half
