ELECTRICITY

Electric current is defined as

• detect electric current

• negative terminal to positive terminal

• positive terminal to negative terminal

• the flow rate of electric charges through a conductor

Electric current flows from

• detect electric current

• negative terminal to positive terminal

• positive terminal to negative terminal

• the flow rate of electric charges through a conductor

Electrons flows from

• detect electric current

• negative terminal to positive terminal

• positive terminal to negative terminal

• the flow rate of electric charges through a conductor

Galvanometer is used to

• detect electric current

• negative terminal to positive terminal

• positive terminal to negative terminal

• the flow rate of electric charges through a conductor

Electricity that flows in a closed path is called a

• path
• current
• circuit

What is voltage measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is current measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is resistance measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

How do you calculate voltage?

• Current X Resistance
• Resistance ÷ Current
• Current ÷ Resistance
• Measure it with a ruler

How do you calculate current

• Resistance X Voltage
• Voltage X Resistance
• Resistance ÷ Voltage
• Voltage ÷ Resistance
