could you please help me solve this?
An electric flat iron with a resistance of 60 ohms, an electric lamp with 50 ohms and a aradio with 1000 ohms are connected in parallel to a 220volt source. if all of the appliances are switched on, solve for
a. current through the flat iron
b. CURRENT THROUGH lamp
c. current through radio
d.total resistance
e. voltage across each resistor
please..i want to follow and know how to answer it so can you show me the solutions....please....

a.) I = V/R
so I(flat iron) = 220/60 = 3.66A
b.) I(lamp) = 220/50 = 4.4 A
c.) I(radio) = 220/1000 = 0.22 A
d.) 1/Rtot = 1/R(flat iron) +1/R(lamp) +1/R(radio)
e.) Because they are in parallal they all have the same voltage of 220V across each

The formula for resistances in parallel is
1/R = 1/60 + 1/50 + 1/1000
Now find the currents.
