Card 1
Question: What are electric circuits?
Answer: Electric circuits are pathways that allow electric current to flow.
Card 2
Question: What is electric current and what is its unit of measurement?
Answer: Electric Current (I) is the flow of electric charge, measured in Amperes (A).
Card 3
Question: What is voltage and what is its unit of measurement?
Answer: Voltage (U or V) is the electric potential difference between two points in a circuit, which drives the current. It is measured in Volts (V).
Card 4
Question: What is resistance and what is its unit of measurement?
Answer: Resistance (R) is the opposition to the flow of electric current, measured in Ohms (Ω).
Card 5
Question: What is Ohm's Law?
Answer: Ohm's Law relates voltage, current, and resistance: U = I · R.
Card 6
Question: What is power in an electrical circuit and what is its unit of measurement?
Answer: Power (P) is the rate at which electrical energy is converted into other forms of energy (e.g., heat, light). It is measured in Watts (W).
Card 7
Question: How can power be calculated for resistive circuits?
Answer: For resistive circuits, power can be calculated using P = U · I, P = I² · R, or P = U²/R.
Card 8
Question: How are components connected in a series circuit?
Answer: Components in a series connection are arranged end-to-end along a single path, meaning electric current flows through each component sequentially.
Card 9
Question: What is a characteristic of current in a series circuit?
Answer: The current is the same through all components in a series circuit (I_total = I₁ = I₂).
Card 10
Question: What is a characteristic of voltage in a series circuit?
Answer: The total voltage supplied by the source is divided among the components, and the sum of the voltage drops across each component equals the total volt
