Find the current.According to Ohm's law, V = ?A bulb has a resistance of 30 Ω and operates at 6 V. Find the current.In a circuit, where is the ammeter connected and where is the voltmeter connected?Two resistors 4 Ω and 6 Ω are connected in series. Find R_total.Two resistors 6 Ω and 3 Ω are connected in parallel. Find R_total.Three resistors of 5 Ω each are connected in parallel. Find R_total.How does the resistance of a wire change if its length is doubled while area stays the same?A 12 V battery is connected across two resistors 4 Ω and 8 Ω in series. The current is:Why is nichrome used for the heating element of an electric iron rather than copper?Joule's law of heating states that H equals:The SI unit of electric power is:A 60 W bulb operates on 240 V. Find the current through it.How much energy in kWh is consumed by a 1500 W appliance running for 4 hours?Two bulbs of 60 W and 100 W are designed for 220 V. Which has higher resistance?If the current through a resistor is doubled, the heat produced in the same time becomes:What is the maximum resistance which can be made using five resistors each of $1/5\ \Omega$?What is the minimum resistance which can be made using five resistors each of $1/5\ \Omega$?Which of the following represents voltage?The resistivity does not change ifTwo resistors of resistance $2\Omega$ and $4\Omega$ when connected to a battery will have
