Y7U5T7 - Understanding Electric Current and Circuits

How is electric current measured?

• In volts (V)
• In watts (W)
• In amperes (A)
• In ohms (Ω)
• In joules (J)

What is the difference between a series circuit and a parallel circuit?

• In a series circuit, components are connected in a line, while in a parallel circuit, components are connected side-by-side
• In a series circuit, components are connected side-by-side, while in a parallel circuit, components are connected in a line
• A series circuit has a higher resistance than a parallel circuit
• A parallel circuit has a higher voltage than a series circuit
• A series circuit splits the current between components, while a parallel circuit allows the current to pass through each component in turn

How does the water circuit model help us understand electric current?

• It uses water as a representation of electric current and different parts of the water system to represent components of the circuit
• It measures the voltage and resistance in a circuit using water
• It demonstrates the flow of electrons through a conductor using water pipes
• It calculates the power consumption of electrical devices using water flow
• It generates electricity through the movement of water in a circuit

What is the unit of measurement for electric current?

• Amperes (A)
• Volts (V)
• Watts (W)
• Ohms (Ω)
• Coulombs (C)

In which type of circuit are components connected side-by-side?

• Parallel circuit
• Series circuit
• Combination circuit
• Open circuit
• Closed circuit

What is the role of a conductor in an electric circuit?

• To provide a path for the flow of electric current
• To increase the resistance in the circuit
• To generate electric current
• To store electrical energy
• To convert electric current into other forms of energy

What happens to the current in a series circuit if one component fails?

• The current stops flowing in the entire circuit
• The current increases in the remaining components
• The current decreases in the remaining components
• The current bypasses the failed component and continues to flow
• The current reverses its direction in the circuit

How does resistance affect the flow of electric current in a circuit?

• Higher resistance decreases the flow of current
• Higher resistance increases the flow of current
• Resistance has no effect on the flow of current
• Higher resistance does not effect the voltage in the circuit

• Higher resistance decreases the voltage in the circuit

What is the purpose of using the water circuit model to understand electric current?

• To visualize the flow of current and the behavior of components in a circuit
• To measure the voltage and current in an electrical circuit
• To generate electricity using water as a conductor
• To determine the resistance of electrical components
• To calculate the power consumed by electrical devices
