1.current=2/3=4 amps
2.60/120=0.5 amps

If the motor presents a 3 ohm load - the current will equal 4 amps.
The 60 watt bulb draws 0.5 amps.
I=amps E=voltage R=resistance P=watts
E=IR R=E/I I=E/R P=IE

volts=amps x resistance
12/3=4 amps

1-)use ohm's law E=IxR, I=E/R R=E/I
E=VOLTS
R=REISTANCE
I=AMPS
SO 12/3=4 amps
2-)In this one you have to use the watt's law that is W=E x I,
E=W/I AND I=W/E
W=WATTS
E=VOLTS
I=AMPS
SO 60/120=.5 amps
