Question 37 1 pts Compared to a single lamp connected to a battery, two identical lamps connected in series to the same battery will carry less current. the same current. O more current. Question 38 1 pts If a compass is moved from the northern hemisphere to the southern hemisphere, its magnetic needle will change direction by 90 degrees. O by 180 degrees. by zero degrees. O depending on where the measurement is taken.

Answer 1

1 Each lamp will have Let the batterey voltage is some resistance say (R) V. current u Single lamp 1,- Ř connected is series, so Now two lamps are the equivalent resistance Req = 2R. Neid current I2 = V 2R. W Iz < I4 o less current S *N E The compus compass will rolate by 180° , whe by 1800 2 Inside the atomic nudeus there is no electrons Do the rotatim of the electrons about the nucleus and about there axis (spin) both will give لأمراض si & magnetic field 1. Both of the other two answers are correct

for a lossless transformate (ideal ene) the primarey Coil the Secondary is power in ceril Same I-4 A Coil v = 110V 'current in the primany Voltage in primany primany cail powe P= IV = 490 W wer & Secondary coil power = 440 watt
