Grade Summary Potential100 Atermpts remaining (0% per attemp) sinO cos0 4 5 6 atanO acotanO sinho coshO tanhO cotanh0 O Degrees Radians 0.Explanation / Answer
a) r4,r5 and r6 are in series = r4+r5+r6
r456 = 56+91+39 = 186 ohm
b) r3 and r456 are in parallele so r3456 =r3*r456/r3+r456 46*186/232 = 36.9 ohm
c) r1,r2 and r3456 are in series
r tot = r1+r2+r3456 = 23+35+36.9 = 94.9 ohm
d) r tot = 94.9 ohm
e) v = ir
f) v = 19.5*94.9 = 1850 V
