3 resistors of 5 ohms,15 ohms, and 30 ohms are connected in series and placed across a 50 volt batt. Find the voltage drops acroos each resistor . And find the current through each resistor

total voltage drop is 50v
total R = 5+15+30=50Ω
current is thus 50v/50Ω = 1A
divide the voltage drop among the resistors
5Ω: (5/50)(50) = 5v
15Ω: (15/50)(50) = 15v
30Ω: (30/50)(50) = 30v
