When you turn the dimmer knob to decrease light intensity then the time constant of the capacitor in the dimmer circuit is decreased. O a. True O b. False To avoid voice signal attenuation (i.e. signal decay) between intercom units, we need: O a. high-Power Audio Amplifier. O b. higher voice loudness. O c. higher cross-sectional area intercom cables. O d. higher output voltage for the intercom transformer. Light switches are usually mounted in the domestic installations: a. near the door (opposite where it opens). O b. all of the answers are correct O c.at 120-130 m from finished floor. O d. at 15-20 m from the edge of the door. When you turn the dimmer knob to decrease light intensity then the time constant of the capacitor in the dimmer circuit is decreased. O a. True O b.
