The potential difference across a bulb is 5 V and the current through the bulb is 5 A. In 10 minutes, how much energy will be transferred by charge passing through the bulb?

A parallel circuit contains three resistors on three separate loops: 50Ω, 100Ω and 150Ω. What is the total resistance?

A series circuit is connected to a 10V battery. The circuit contains 3 resistors: a 10Ω, a 20Ω and a 50Ω. What is the voltage drop across the 50Ω resistor?

A lamp has a potential difference of 20 V, and a charge of 25 C flows through it if it is left on for 50 seconds. What is the resistance of the lamp?

40 coulombs passes through a lamp as it converts 1000J of electrical energy. The current flowing through the lamp is 5 amps. What is the resistance of the lamp?

In one household, a TV with a power rating of 500W is used for 4 hours a day, a fan with power rating 100W is used for 8 hours a day, and a kettle with power rating 1500W is used for 30 minutes a day. How much did the household pay for electricity in the month of April? Note: Ft rate = 0.1 THB/kWh and the VAT rate is 7%.
