I can't finsd it either....as I recall it was +-1 +- i (four solutions)
DO a search for this Q and answer.....it has been posted multiple times in recent months....
A to B would be sqrt (20^2 + 48^2 + h^2) h was not given in your screenshot sorry.....h = 10 in your typed version of your Q
Using Pythag Theorem
sqrt ( 20^2 + 48^2) = 52 ft
NO.......
Current in the circuit v/r = i
45/(20+30+45) = 473 mA
Votage across R3 = IR = .473 * 45 = 21.3 v
ALL of the voltage will be dropped around the circuit .....45 v will be dropped
R3 portion will be a fraction 45 / (20+30+45) x 45 v = 21.3 v
TRUE !! Keeping it simple .... and potentiometers can be used as rheostat....
We already determined the current through the circuit (in a previous question)
I R4 = Voltage R4 = 5 ohms and current was from previous Q
R2 is the smaller and thus I2 will be the larger
Sure! Just hangin' at the house makin' beer......
HINT: For parallel circuit resistors .....(they all have the same voltage applied across them) the smaller the resistor, the larger the current
