2)Ammeter 1 reads 6A and Ammeter 3 reads 2A. Battery 1 supplies 12V. a)What will be the reading on Ammeter 4 and 2?
b) What is the résistance of the light bulb?

answer; (arch); good luck

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
